Just received my delta 2 today with the RBA base.
A couple issues with it:
- Machine oil or whathever factory smell it was, eww. Thankfully it's gone now
- This thing hits like a fucking truck, even diluting my 6mg juices with glycerin, holy shit, too harsh
- Stock coils have a LOOOOOONG delay before firing up. At first I tought my shiny new iStick 50 was defective
So yeah, figured pretty quickly the stock coil head wasn't for me, I prefer something smoother.
I built the RBA using twisted kanthal (can't fucking remember if it was 26? I think). Wicked it with rayon (fiberfreaks) and it's basically where I want it now. Getting about as much vapor as the stock heads maybe a tiny bit less I don't know, and flavor is good even tho I'm using juices diluted with pure glycerin. Using halo malibu and alice twas brillig mixed with about half glycerin, which should be something like 80% glycerin in the end. It wicks fine up until 40 watts. At 50 it requires shorter puffs, but I guess I could always hack the juice flow base if I really wanted that. I don't, though. Not sure how much the rayon helps with the wicking part.
I will keep my nautilus mini around tho because, yeah, this is not a "living among your peers" type thing. You fog up the place bigtime.
TLDR: stock heads are too harsh and fire too slow, a good build on RBA is better for me.
